To aZZ whom it may concern.-

Be it known that I, JAMES MASON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in a Machine for Cutting Rosettes in Corner Casing-Blocks forDoor-Frames, Book- Cases, and other Articles, of which the following is a specification.

I-Ieretofore in machines for cutting rosettes on corner casing-blocks the cutting-tools of the machine have been rapidly rotated in such manner that the ends thereof come in contact with the corner casing-block, which has been firmly held in a sliding frame when slid forward together with such frame toward the rotating tools, and the ornamentation desired in the corner casing-block thereby out. After the cutting of the ornamentation thereon the corner casing-block has been removed from the sliding frame and secured on a rotatable head or disk of a second machine and by the turning of such head or disk made to rapidly revolve and by the holding of a piece of sand-paper thereto properly sandpapered. The corner casing-block is thus completed and then removed from the rotating head or disk.

The purpose of this invention is to obtain a machine for cutting such corner casing blocks, wherein the corner easing-block shall be rotated while the ornamentation thereof is being cut thereon by the tools, such tools not rotating and being firmly secured in a sliding frame and adapted to be slid into contact with the revolving corner casingblock. The ends of such tools are thus brought properly into contact with the face of the corner casing-block, and the cm amentation cut thereon, after which the cuttingtools are slid back from contact with the face of the corner casing-block and sandpaper applied thereto while such corner casing-block is still revolving and the block completely finished before being taken from the machine.

By this machine I am enabled to make corner casing-blocks having the same designs in the ornamentation thereof as those heretofore made and in much less time.

I have illustrated my invention by the drawings accompanying and forming a part of this specificatiomin which Figure 1 is an elevation of a machine embodying the invention; Fig. 2, a plan thereof;

Fig. 2 in the direction of the arrows; Fig. 5,

a central sectional view of a rotatable head or disk on which the corner casing-block is held and with which it rotates while the ornamentation thereon is being cut; Fig. 6, a front elevation of such rotatable head or disk; Fig. 7, a front elevation of one of the cuttingtools; Fig. 8, an end elevation of the tool illustrated in Fig. 7; Fig. 9, a front elevation of the other of the cutting-tools of the machine; Fig. 10, an end elevation of the tool illustrated in Fig. 9; Fig. 11, a front elevation of a corner casing-block cut by the tools illustrated in Figs. 7, 8, 9, and 10, used with or on the machine illustrated in Figs. 1 to 6, both inclusive; and Fig. l2,asectionalviewof such cornercasing-block. Fig. 13 is a top plan view of a modification of the invention, which permits the rotating corner casing-block to approach rigidly-held stationary tools. Fig. 14 is a sectional view thereof on linell 14 of Fig. 13, viewed in the direction of the arrows. view on line 15 15 of Fig. 13, viewed in the direction of the arrows; and Fig. 1G is a side elevation of a lever forming part of the modification by which the lateral movement of the rotatinghead-block is secured while the headblock is rotating.

Similar letters of reference indicate the same parts where more than one view thereof is shown in the drawings.

A B is the frame of the machine, part A being that part of the frame in which the rotatable parts of the machine are placed, and part B that part whereon the sliding parts of the machine are placed.

1) b are grooves ortracks wherein or whereon the slidinghead 1) moves. The cutting-tools of the machine are firmly held in the sliding head I).

C is a rotatable shaft on which are rigidly secured pulleys C 0 C C is a loose pulley or idler on shaft 0.

Fig. 15 is a sectional- C is a belt by which the machine is driven.

G is a belt-shifting device having handle 0 thereon, by which the belt 0 is shifted from the idler O to driving-pulley C and back, as desired, such belt actuating the machine when on the pulley 0 but not driving the machine when on idler C D is a rotatable shaft having pulleys D D rigidly secured thereto and having head or disk E at one end thereof, also rigidly secured thereto.

cl is a driving-belt extending over pulleys C D or C and D as preferred. This belt d is illustrated in the drawings as extending over the pulleys O and D.

e e are grooves in head E, and F F are blocks sliding in these grooves.

ff are bolts extending through the head E and through the sliding blocks F F, by means ofwhich the sliding blocks are firmlysecured in any desired position in the grooves c e.

In the modification illustrated in Figs. 13 and 16, both inclusive, E is the revolving wheel to which the corner casing-block to be ornamented by the rosette is firmly secured, and with which it rotates in the cutting, and E is the hub thereof extending on shaft D Hub E is made to revolve with shaft D by the key or spline D which extends into the shaft longitudinally therewith and into the hub E 'of the wheel E, while at the same time the wheel E and hub E may slide or beslid on the shaft D and on the key or s'plineD. The mannerin which the position of the wheel E is determined and controlled (longitudinally on shaft D is by putting the groove E around the hub E and placing the fork of the pivoted lever J (such fork being lettered J in the groove E Lever J is pivoted on point J 3 on standard J such standard being rigidly secured to the frame of the machine.

G H- are cutting-tools held firmly in sliding head or block b by plate I, which is clamped to the sliding head I) by bolts I.

J is a handle by which the sliding block b is moved forward and backward on part B of the frame. K is the corner casing-block, and K K K K are the severalbeads and grooves forming the ornamentation of such corner casing-block.

' k k k are the different members forming the ornamentation K.

The difficulty heretofore experienced in cuttin ga corner casing-block on a machine Wherein such corner casing-block rotates and the cutting-tools do not rotate has been that the circular beads or moldings on such corner casing-block, particularly the one standing out from the main body of the design, has been split, out, broken, or torn out from the cornercasing-block, especially in the parts thereof crossing the grain of the wood of the block, and inorder to obviate this difficulty I have, in addition to the devices hereinbefore described, found it necessary to use more than one cutting-tool. I have heretofore used two cutting-tools, one of such cutting-tools cutting the ornamentation on the corner casingblock from the center thereof to about halfway out of such ornamentation and the other tool cuttingthe ornamentation the remainder of the way out. In using two cutting-tools for thus cutting the ornamentation of the corner casing-block one thereof must be secured in the sliding head I) so as to cut on the bottom edge thereof as the corner casing-block revolves, carrying the part of such block to be cut thereby up toward the tool, and the other thereof secured in such sliding head I) so as to cut on the upper edge thereof as the corner casing-block revolves, bringing the portion thereof to be cut down toward such tool, and such tools being so placed in the sliding head I) that one thereof is on one side of the center of the ornamentation and the other on the other side thereof. WVhen arranged in this way, one of the tools will cutthe ornamentation from the center thereof about half-way out and the other the remainder of the distance.

In corner casing-blocks having the'kind of ornamentation thereon which this machine is adapted to out there is a circular bead or molding extending out from the body of the ornamentation at about half-way of the dis tance from the center to the edge thereof, and these tools being arranged, as described, on each side of the center of the corner casing-block and so adapted to cut the ornamentation of the block. One of such tools cuts one-half of this circular bead or molding and the other thereof cuts the remainder of such bead or molding, and the liability to tear out pieces or portions of the circular bead or molding and thereby cause ragged and unsightly blotch'es therein, particularly at the point on the corner casing-block where the cutting-tools cross the grain of the wood of the block, is thereby almost entirely done away with. In addition to thus cutting the ornamentation on the corner casing-block by two tools, as described, one of such tools (the .one lettered Gand cutting the ornamentation from the center out toward the periphery thereof) is composed of two parts or portions, the one integral with the other, but placed in a plane intersecting the plane of the other at a very obtuse angle on the inside of the tool,

'or that side on which the cutting-edge is placed, so that the cutting-edges of each part or portion of suchtool come in contact with and against the face of the corner casing-block in a suitable manner to best cut the ornamentation thereon without tearing the wood from the block, and the other of such tools (lettered H) has the cutting-edge thereof turned at an angle to the shank of the tool. The two parts or portions of the tool G are lettered, respectively, g g. The cutting-edge of the part or portion 9 is lettered g and the cutting-edge of the other part or portion is lettered 9 Cutting-edge 9 cuts the center ornamentation K in the corner casing-block K, as illustrated in Figs. 11 and 12. Cutting-edge g cuts the circular groove K and cutting-edge 9 outs about one-half of the circular bead or molding K h is the shank of tool II. This cutting-tool H has cutting-edges h h 7L3 7%. Outting-edge h cuts the outer half of the circular head or molding K and cutting-edges 712 72 h cut, respectively, members k 70 of the beading or ornamentation K.

It is not to be understood that this machine is adapted to out only the particular ornamentation upon the corner casing-block illustrated by Figs. 11 and 12 of the drawings and herein described, as by changing the shape of the cutting-edges of the tools, or one of them, any desired shape of turned mold can be made, the ornamentation produced thereby having a different appearance from that illustrated in Figs. 11 and 12 of the drawings; but the use of two cutting-tools and the placing of the cutting-edge of such tools in the proper angle to the horizontal plane extending through the center of the ornamentation on the face of the block as such block is being revolved and cut in the machine should in all cases be preserved, and also the projecting circular bead or molding corresponding with the bead or molding K of Figs. 11 and 12 must be out about one-half with one of the tools and the other half thereof with the other of the tools, placed as described in the sliding corner casing-block of the machine, so that one of such tools shall have its cutting-edge on the lower side thereof and the other 011 the upper side thereof, one being on one side of the center of the ornamentation of the corner casingblock and the other on the other side thereof.

In order to operate this machine, corner casing-block K is placed on disk E and clamps or sliding blocks f f f f secured in place against the corner casing-block K to hold it in position. Belt (3 is shifted from the loose pulley 0 onto pulley C and the block thereby rapidly rotated. Sliding head b is then brought forward by handle J and the cutting-edges of the tools G H brought against the block K and the ornamentation thereon cut by such tools, after which the sliding head Z2 is slid back and the face of the block: properly sandpapered while rotating and then removed from the machine in a finished condition.

It will be evident to those skilled in the art of turning wood that the face-plate E can be put on a wood-turning lathe and the cutters secured in a head adapted to be slid on the frame of the lathe, and that the result at tained will be the same as that attained in the machine herein described. It is evident, too, that if the face-plate or head E is feathered on shaft D so as to rotate therewith, but adapted to be longitudinally movable on such shaft D, the cutting-tools and sliding head 6', in which they are held, may be rigidly held in one position and the face-plate or head E,with

' the block K secured thereon, slid up to the cutting-tools; but such a change in the construction of this machine would involve no invention, as when the block on which the rosette is to be cut and the tools cutting the rosette thereon are considered solely with reference to each other it makes no difference whether a rapidly-revolving block is made to approach rigidly-held and stationary cuttingtools or whether the tools held rigidly and stationary, except so far as approaching the rapidly-revolving block, are made to approach such rapidly-rotating block, and a construction wherein the rotating block can be made to approach rigidly and stationary held cutting-tools is illustrated in Figs. 12 to 15, both inclusive, in the drawings, and the machine as so constructed would embody the hereindescribed invention.

Having thus described my invention, what I claim and desire to secure by Letters Patent of the United States, is-

In a machine for cutting corner casingblocks, the combination of a rotatable faceplate adapted to have secured thereon a corner casing-block with cutting-tools and a sliding head, one of such cutting-tools secured in such sliding head with the cuttingedge thereof on its under side and the other one with its cutting-edge on the upper side thereof, and one of such tools extending from thecenter of the ornamentation produced on the corner casing-block out toward the circumference of such ornamentation on one side of such center and the other placed on the other side of the center of such ornamentation and extending from about half-way out thereof to the circumference thereof, whereby when the face-plate and block are rotated and the outting-tools are slid against the block one of such tools will out about one-half of the ornamentation on the block and the other of such tools will simultaneously out the other half thereof, substantially as described.
